NEEDLE-THREADER.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed July 29, 1912, Serial No. 712,160. Renewed. April 10, 1915. Serial No. 20,547.

To all whom it may concern:

Be it known that I, LUDVIG Ros'rAn, a citizen of the United States, residing at Vermilion, in the county of Clay and State of South Dakota, have invented certain new and useful Improvements in Needle- Threaders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in needle threaders.

One object of the invention is to provide a needle threader having an improved construction and arrangement of needle holding mechanism and an improved means for engaging the eye of the needle and drawing the thread therethrough.

Another object is to provide a needle threader which will be simple, strong, durable and inexpensive in construction, efficient in operation, and with which any ordinary size and style of hand or machine needle can be readily used.

\Vith these and other objects in View, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a front view of the threader with a needle in position to be threaded; Fig. 2 is a vertical section with the threading member projected through the eye of the needle; Fig. 3 is a side view showing the threading member retracted and the thread drawn through the eye of the needle; Fig. 4 is a rear view of the threader; Fig. 5 is a horizontal sectional view taken on line 55 of Fig. 1; Fig. 6 is a vertical cross section taken on the line 6-6 of Fig. 1.

My improved needle threader comprises a plunger guiding and supporting plate 1, having its upper and lower edges bent inwardly to form upper and lower guide flanges 2 and 3 between which is slidably mounted the threading member or plunger 4 of the device. One end of the plate 1 is beveled on its upper and lower edges to form a tapered point 5, in the lower side of which is formed an inwardly projecting notch 6. Theinner end of the notch 6 is formed on an angle, as shown at 7, and in said end of the plate 1 above the inner end of the notch 6 is a view opemng-S.

In beveling or pointing the end of the plate 1, the ends of the flanges 2 and 3 are cut away or separated from the body of the plate, and said ends of the flanges are tapered to form points 9 as shown. On the upper edge of the pointed end of the lower flange 3 opposite to the inner endof the notch 6 in the plate 1 is formed an upwardly projecting thread guiding lug 10, at the inner end of which and in the upper edge of the lower flange 3 is a thread guiding notch 11. The inner end of the lug 10 is bent outward to a slight extent as shown, to facilitate the passage of the thread around it.

Arranged transversely across the plate 1 near the pointed end thereof, and secured between the flanges 2 and 3 and the adjacent side of the platel, is a tube or socket 12,- in one side of which, adjacent to the inner end of the notch 6 is formed a beveled recess 13 to receive the thread when engaged with the notches 6 and 11.' The lower end of the tube or socket 12 is closed, and in it is formed a depressed seat 14 which is elongated transversely so that it receives the end of the needle when engaged with the tube, and holds said end in position toreceive the thread, as will be hereinafter more fully described.

In the tube 12 opposite the recess 13 is a slot 15 with which is adapted to be engaged a thin tapered thread engaging hook 16 formed on or secured to the inner end of the plunger 4 as shown.- On the plunger 4 at the inner end thereof and adjacent to the lower edge of the upper flange 2 is astop stud 17 which, when the plunger has been retracted to its full extent, engages a stop lug 18 on the inner edge of the flange 2 at the inner end thereof as shown.

In the operation of the'device for threading an ordinary hand sewing needle, the eye end of the needle is inserted in the tube or socket 12 until said end of the needle comes into engagement with the seat 14, in which position the eye of the needle will be in the same plane as the recess in the tube. After the needle has thus been engaged with the tube 12 the plunger is projected until the hook on the inner end thereof passes through the slot 15 in the tube and through the eye of the needle. When the plungerhas been projected to bring the hook 2 into this position, the thread is passed 1nto the notch 6 and drawn upwardly into the angular inner end thereof and around the lug 10 and into the notch 11. When in this position the thread will be brought across the top of the hook 16 so that when the plunger is retracted the hook will draw the same through the eye of the needle and through the slot 15 in the tube 12. ,Vhen the thread has thus been drawn through the eye of the needle and slot in the tube 12 the thread is disengaged from the hook 16, whereupon the needle may be pulled out of the tube or socket 12', carrying the thread therewith, which latter is drawn through the tube until a sufiicient length is obtained, after which the thread .is cut from the spool in any suitable manner.

In threading a machine needle the pointed end of the plate 1 and the pointed ends of the flanges 2 and 3 form a space to receive the needle in such manner that the point of the needle will be disposed between the lower flange 3 and the adjacent side of the plate 1 and will rest in the groove formed by the flange 3. When in this position the eye of the needle will be disposed in line with the recess 13 and the slot 15 in the tube 12 so that when the plunger is projected the hook 16 will pass through the slot in the tube and through the eye of the needle. hen the plunger hook has thus been engaged with the needle the thread is engaged with the notches 6 and 11 in the plate 1 and flange 3 and with the hook, whereupon when the plunger is retracted the thread will be drawn through the eye of the needle in the same manner as described in connection with the threading of an ordinary hand sewing needle. The seat 14 in the closed lower end of the tube or socket 12 and at the lower end of the recess 13 is elongated transversely so that when the eye end or the needle is dropped into the tube the needle will be turned to bring the eye therein into register with the slot in the tube 12 so that thehook on the end of the plunger will pass freely through the eye of the needle.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood. without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is:

A needle threader comprising a plate having its edges bent inwardly to form guide flanges and having one end pointed and provided. with a notch and a view opening, a needle holding tube secured in the guide flanges of said plate and having therein a recess, points on said flanges and forming between themselves and the adjacent end of said plate a needle receiving space, a plunger slidably mounted in the guide flanges, and a thread engaging hook carried by said plunger and adapted to be projected through the recess in said tube and through the eye of a needle.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
